Deaf people want to communicate remotely with sign language. Sign language requires sufficient video quality to be intelligible. Internet-based real-time video tools do not provide that quality. Our approach is to use ...

Mobile devices and mobile networks are becoming more data-centric (evident in Japanese I-mode) even as mobile network voice Average Revenue Per User are declining, new stream of data services are required which must take ...

As the volume of information available on the Web information systems is growing continuously, browsing
this content becomes a tedious task given the presentation of data that does meet user's aims and needs. In this
paper, ...

One of the major constraints of wireless sensor networks is limited energy available to sensor nodes because of the small size of the batteries they use as source of power. Clustering is one of the routing techniques that ...

The history of the management of information systems includes many ideas that were intended to
simplify the complexities of the management task, but there is still a great deal of wasted investment that
produces no ...

The South African Deaf community has very limited telephony options. They prefer to communicate in sign language, a visual medium. Realtime video over Internet Protocol is a promising option, but in reality, the quality ...

One way for Deaf people to communicate with hearing people over the telephone is to use a voice relay. The service is often provided with a human relay operator that relays text into voice, and vice versa, on behalf of the ...

Universities are increasingly required to respond to the ever evolving needs of an ever more sophisticated and globalised workplace, which requires well-rounded workers with more than mere technical knowledge. Employers ...

Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centered approach to learn how interaction techniques can compensate for poor communication across ...

This paper describes the design and evaluation of two browser-based video communication prototypes that support sign language communication between Deaf people. The research explores combinations of technologies, protocols ...

This paper describes work in progress to to provide browser-based sign language communication for deaf users. The paper introduces the communication requirements for a disadvantaged Deaf community in Cape Town, describes ...

This paper describes work in progress on call capacity optimization for voice over Internet Protocol on wireless mesh networks. In a developing country such as South Africa, evidence has shown that rural inhabitants find ...

This paper discusses how an Instant Messaging application on a computer can use Bluetooth in order to provide vibration notification on a mobile phone. The initial motivation was to aid Deaf1 office workers to know when ...

We describe designing an asynchronous, oral repository and sharing system that we intend to suit the needs and practices of rural residents in South Africa. We aim to enable users without access to personal computers to ...

Given the needs for a clean and easy way to maintain and secure powering wireless networks in rural areas and to gen- erate revenue to guarantee the sustainability of its intended goals, an innovative approach to leverage ...

There is a growing interest in the use of context-awareness as a technique for developing pervasive computing applications that are
flexible and adaptable for users. In this context, however, information retrieval (IR) ...

The process of community-based co-design is one that explores various solution configurations in a multi-dimensional design space whose axes are the different dimensions of requirements and the various dimensions of designer ...
